I would like some feedback on the gear list I have created so far for conditions down to 20F. I have not listed a pack, shelter, or bag as I will be deciding and getting new ones soon. I will also be getting some microspikes for snow and ice. The primary goal of this list is to be able to just pick up the pack and some food and head out the door for a few weeks if need be. Where can I cut and what am I missing? The pad is not an option.
